ROTATING PLATFORM.

Application filed September 22, 1923. Serial No. 664,208,

To all flo/1,0m t may' concern:

Be it known that I, ALFRED HAROLD Hunan, a subject of the King of Great Britain, residing at Manx Villa, Oakington Avenue. lVen'ibley Park, Middlesex, England, have invented new and useful Improvements in or Relating to Rotating Platforms, of which the following is a specification. t

This invention relates to improvements in rotating platforms and .is particularly applicable for displaying goodsv in shop windows, and has for its object a simple and cheap method of producing the retation of the platform.

According to this invention platform is provided on its underside with vanes or the like, while an electrically driven fan is arranged within a casing surrounding the vanes. Preferably means are provided for governing the speed of rotation of the platform.

The invention is illustrated in the accompanying drawing in which Figure l is a section and Figure 2 a plan of an arrangement forming the subject of this invention.

Referring to the drawing, the casing con sists of a basey plate a and sides b. c is the platform provided on its underside with a series of vanes or buckets d and d. As illustrated there p are three series of buckets, viz the series d and the two series d arranged staggered. engages with a spindle e of a train of wheels terminating in a vane governor g. The mechanism is mounted on a pedestal la.. z' is an electric fan rotatably mounted in a frame y' to facilitate its positioning to its mostV effective angle.

The platform e" yair currents initially confined within the casing. g

2. The combination of a platform provided on its underside with a series of concentrically arranged propelling vanes, a support below the platform on which it is pivotally mounted to turn, a casing surrounding the platform and the support and providing a closed chamber below the platform, and an electrically driven fan within the casing and serving to initially confine and distribute currents of air throughout the casing. i

3. The combination of a platform, proyvided on its underside with propelling vanes, Va support below the platform on which the latter is pivotally mounted, a casing surrounding the support and the platforrmany electrically driven fan within the casing, and a frame within the casing to which the electrically driven fan is pivotally connected.

In testimony that .I claim the foregoing as my invention I have signed my name this 14th day of August. 1923.v
